Peanut Butter Oatmeal Bars
- 1/2 cup unsalted butter (softened to room temperature)
- 1/4 cup granulated sugar
- 1/3 cup packed brown sugar
- 1 large egg
- 1/2 tsp vanilla extract
- 1/3 cup creamy peanut butter
- 1 cup whole wheat flour (can also substitute all-purpose flour; if so, add 1/4 tsp salt and 1/2 tsp baking soda)
- 1 cup old-fashioned or quick oats
Peanut Butter Streusel
- 1/4 cup whole wheat flour
- 1/4 cup packed brown sugar
- 2 tbsp creamy peanut butter (softened to room temperature)
- 1 1/2 tbsp unsalted butter
Peanut Butter Drizzle
- 1/3 cup powdered sugar
- 1/4 cup creamy peanut butter
- 1–3 tbsp milk (add 1 tbsp at a time, additional milk may be added until drizzle consistency is reached)
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper or spray it with non-stick cooking spray to ensure easy removal of bars.
- Cream Butter and Sugars: In a large mixing bowl, use a hand mixer or stand mixer to cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy, about 2-3 minutes.
- Add Wet Ingredients: Beat in the large egg, creamy peanut butter, and vanilla extract until the mixture is smooth and well combined.
- Incorporate Oats and Flour: Gently stir in the oats by hand until evenly distributed. Then, add the flour (and salt and baking soda if using all-purpose flour) and mix just until combined to avoid overmixing and keep the bars tender.
- Spread Batter: Evenly spread the prepared batter into the lined or greased baking pan, smoothing the top with a spatula.
- Make Streusel: In a separate bowl, combine the whole wheat flour, brown sugar, creamy peanut butter, and softened butter for the streusel topping. Mix until it forms coarse crumbs but is not too wet.
- Top with Streusel: Sprinkle the peanut butter streusel evenly over the batter in the baking pan to ensure an even crunchy topping.
- Bake: Place the pan in the preheated oven and bake for 25-28 minutes, or until the bars are lightly golden and a toothpick inserted in the center comes out mostly clean.
- Cool Before Drizzle: Remove from oven and let the bars cool completely for 15-30 minutes to set before adding the drizzle.
- Prepare Drizzle: While bars are baking, mix powdered sugar, creamy peanut butter, and 1 tbsp milk in a small bowl. Add additional milk 1 tbsp at a time until the drizzle reaches a smooth consistency. Chill the drizzle in the refrigerator until ready to use.
- Apply Drizzle: For a neat drizzle, transfer the peanut butter drizzle into a piping bag or Ziploc bag with a small corner snipped off, then drizzle over the cooled bars evenly.
- Final Set and Serve: Allow the drizzle to set for about 10 minutes. Cut into desired sized bars and serve. Enjoy your crunchy, chewy peanut butter oatmeal bars!
- Storage: Store any leftover bars in an airtight container at room temperature for up to 5 days to maintain freshness.
Notes
- You can substitute all-purpose flour for the whole wheat flour by adding 1/4 tsp salt and 1/2 tsp baking soda to the batter for best results.
- Use creamy peanut butter for a smoother texture in the bars, streusel, and drizzle.
- Adding milk gradually in the drizzle helps achieve the perfect pouring consistency without being too runny.
- Quick oats can be used instead of old-fashioned oats, but the texture will be slightly different (softer).
- Letting the bars cool completely before adding the drizzle prevents it from melting and running too much.
- You can store leftover bars in an airtight container at room temperature; they are best consumed within 5 days.
